 Again, think of using [paper & pencil first](http://alistapart.com/article/paperprototyping).
 
-We recommend first and foremost open source software such as [Inkscape](https://inkscape.org/en/) or [Pencil](http://pencil.evolus.vn/) (a [complete list](http://opensourcedesign.net/resources/#design-tools)), but at the same time we know most of them are behind popular software for web design workflows. You can use any design software that's available to you. Just make sure to include editable exports (SVG, PDF, EPS) along with your source files.

-#### Gravit Designer
-
-Multiplatform and can be used online too ([freeware](https://discuss.gravit.io/t/how-does-gravit-make-money/3002/2)).

-#### Sketch
-
-Some pointers to open files from [Sketch](https://www.sketchapp.com/):
-
-- [Sketch-react](https://zjuasmn.github.io/sketch-react/): Web app that supports multiple pages. Admits uploading files and referencing by URL.
-- [Sketch Web Viewer](https://animaapp.github.io/sketch-web-viewer/): Web app that supports uploaded files.
-- [Figma](https://www.figma.com/): Powerful tool for UX and UI design. It has a web interface as well as desktop apps (internet connection required). It’s free for individuals.
-- [Photopea](https://www.photopea.com/): Free web editor for Sketch, Photoshop and Gimp files. The only editable export format is PSD, which may not be fully compatible for Sketch import.
-
-We recommend installing the following Sketch plugins to improve your design
-workflow. Don’t forget to read the documentation of each plugin to use them
-properly. If you’d like to recommend a plugin, please [create an issue](https://PeerTube.com/PeerTube-org/PeerTube-design/issues/new).
-
-- [Relabel Button](https://github.com/kenmoore/sketch-relabel-button): Prompts for a button’s new label, applies the text, resizes the button background, and repositions any other interior elements while maintaining the existing padding. It’s essentially awesome voodoo magic.
-- [Git Plugin](https://mathieudutour.github.io/git-sketch-plugin/): A Git client built right into Sketch. The plugin really improves the review process by exporting an image for every part of the design.
